Upon further review, I think I know what's going on, but I'm not sure
what to do about it.

I have the files in /var/cache/crafty set up as configuration files.
If I do a "--purge" and then reinstall the crafty package, I get the
right file ownship and permissions.  I also get the right permissions
if a remove the configuration status of the files in /var/cache/crafty
and do an upgrade.

So, I guess I was just seeing an illusion.  I thought the files were
being replaced when they weren't because they were configuration
files.

I'm not sure what to do though.  The files in /var/cache/crafty really
should be configuration files, but I don't know how to fix the
ownership or permissions of those files when the user does an upgrade
except to add something to postinst.
